BYM10-1000-E3/97

Overview

The BYM10-1000-E3/97 is a surface-mount glass passivated junction rectifier from Vishay General Semiconductor. It utilizes the Superectifier structure and operates in the MELF (DO-213AB) package. The device supports a maximum average forward rectified current of 1.0 A and a peak forward surge current of 30 A. It withstands a maximum repetitive peak reverse voltage of 1000 V, with a maximum DC blocking voltage of 1000 V. Electrical characteristics include a maximum instantaneous forward voltage of 1.2 V at 1.0 A, a maximum DC reverse current of 10 μA at rated voltage, and a typical junction capacitance of 8.0 pF. Thermal resistance from junction to ambient is typically 75 °C/W, and the operating junction temperature range extends from -65 °C to +175 °C.

Feature Summary

• Superectifier structure designed for high reliability under demanding conditions
• Glass passivated junction providing low leakage current and low forward voltage drop
• High forward surge capability suitable for transient protection scenarios
• Meets MSL level 1 per J-STD-020 standards for automated placement compatibility

Applications

• General purpose rectification in power supplies
• Inverter and converter circuits
• Freewheeling diodes for consumer electronics
• Automotive electronic systems
• Telecommunication equipment

Procurement Notes

Verify that the ordering suffix /97 corresponds to the 13-inch diameter plastic tape and reel delivery mode with a base quantity of 5000 units. Confirm compliance with RoHS directives and JESD 201 class 1A whisker test requirements via the E3 suffix. Ensure the component meets UL 94 V-0 flammability ratings for the molded epoxy casing before final procurement integration.

Selection Notes

Select this component when a 1000 V repetitive peak reverse voltage rating is required alongside a 1.0 A continuous forward current capacity. The MELF (DO-213AB) package is appropriate for applications needing compact surface-mount solutions with high thermal stability up to 175 °C. Consider the 1.2 V maximum forward voltage drop for efficiency calculations and verify that the 30 A non-repetitive surge current aligns with circuit transient requirements.

Part Context

This part belongs to the BYM10 series of Superectifier diodes manufactured by Vishay General Semiconductor. The GL41x designation identifies the specific polarity band coding within the MELF form factor. The product line emphasizes high reliability through its glass passivation process and is intended for general-purpose rectification across industrial, automotive, and telecommunications sectors.

Replacement Considerations

Cross-reference with other Vishay BYM10 variants sharing the DO-213AB package if different voltage ratings are needed. Verify pinout compatibility and thermal resistance specifications against alternative manufacturers' MELF rectifiers. Ensure any substitute maintains the 1000 VRRM rating and 1.0 AIF(AV) current handling capabilities.
